Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a tape seedling that forms a series of tape seedlings by arranging the seedlings in strips and applying tape to both sides of the row of seedlings in order to make it easier to plant the strawberries and other seedlings by a transplanter. Regarding manufacturing machines.

[0002]

[Prior art]

 A tape seedling manufacturing machine provided with a sticking device for sticking tape on both sides of a seedling row and a drum for winding the stuck tape seedlings in a seedling feeding section is disclosed in Japanese Patent Application Laid-Open No. 4-18 of the present applicant. It is already known from Japanese Patent Publication No. 7004.

[0003]

[Problems to be solved by the device]

 The above-mentioned tape seedling making machine stops the drive of the seedling making machine when the operator visually checks the winding amount of the tape seedlings to be wound on the drum, and when it judges that the predetermined amount has been wound on the drum. I replaced it with a different drum. As a result, the worker has to constantly work while monitoring the winding amount on the drum. Also, as the amount of winding on the drum is left to the operator, the amount of winding on each drum becomes uneven, and when the tape seedlings are pulled out from the drum and then stored in the storage box for the transplanter, There was a problem that the seedlings were too long to stick out of the storage box, or on the contrary too short. Moreover, if the tape seedlings are protruding from the storage box and the storage box is placed on the auxiliary seedling table of the transplanter and planted and run, the tape seedlings will drop from the storage box due to machine vibration, and the seedling splicing will also occur. Therefore, when replacing the storage box, the protruding seedlings make it difficult to perform the replacement work. Furthermore, transplanters are often used for multi-row planting, and if the length of the tape seedlings in the storage box is different, the splicing timing will be different for each row. There was a drawback that the replacement frequency of trees increased and efficient planting work could not be performed.

[0004]

[Means for Solving the Problems]

 According to the present invention, a sticking device for sticking tape to both sides of a seedling row, a drum for winding the stuck tape seedling, and a tape seedling wound on the drum are provided in the seedling feeding section of the seedling carrier. A sensor for detecting the winding amount is provided, and when a predetermined amount of tape seedling is wound on the drum, the sensor detects it and activates an alarm device to notify the worker that it is time to replace the drum. Alternatively, the above-mentioned problem is solved by stopping the drive of the seedling producing machine to prevent further winding on the drum.

[0005]

[Action]

 The seedling transport device transports the seedling rows arranged in strips and sends them out from the seedling feeding section, and at the seedling feeding section, the derived tape is attached to both side surfaces of the seedling row, or If necessary, in order to prevent detachment of the seedlings from the tape, a needle rotates around the seedling row, pulls out a thread, and winds it around the tape. Then, the produced tape seedlings are sequentially wound up on a drum provided on the lower side of conveyance. In addition, when a certain amount of tape seedlings are wound on the drum, a sensor that detects the amount of winding detects this and activates an alarm to notify the operator that it is time to replace the drum, or seedling production Stop the machine drive and prevent further winding on the drum. Therefore, the worker interrupts the work, removes the drum that has been wound up, and replaces it with a new drum. Therefore, tape seedlings are always wound in a fixed amount on the wound drum, and during subsequent storage work of the tape seedlings in the storage box or planting work by the transplanter, obstacles caused by the tape seedlings are obviated. Prevents smooth planting work.

 One embodiment of the present invention will be described with reference to the drawing machine for producing tape seedlings of strawberries shown in the drawings. In FIG. Therefore, the strawberries seedlings whose roots have been loosened by the loosening machine 1 are supplied to the taping machine 2. As shown in FIG. 1 or FIG. 2, the taping machine 2 has pulleys 4 and 4, which are slightly inclined rearward, on the start end side and the end end side of the machine frame 3. A conveyor belt 5 is stretched around the pulleys 4 and 4, and the seedlings carried out from the disintegrator 1 are automatically supplied to the conveyor belt 5. In addition, a seedling stand 6 on which the rooted strawberries are placed is provided above the conveyor belt 5 on the inclined side, and the operator can set the seedling stand 6 depending on whether the seedlings on the conveyor belt 5 are excessive or insufficient. The seedlings are replenished on the conveyor belt 5. Further, a root transport belt 5a for receiving and transporting the roots of the seedlings is provided below the transport belt 5 on the inclined side. Further, a pressing belt 7 is provided on the upper portion of the feeding side of the conveying belt 5 so as to be parallel to the feeding belt 5, and the pressing belt 7 is stretched by pulleys 8 and 8 to form a row with the lower conveying belt 5. The seedlings are sandwiched and transported. In addition, 9 is a circular saw-like cutter provided on the upper side of the inclination of the conveyor belt 5, and cuts the tips of the conveyed seedlings.

On the other hand, reels 11, 11 on which the winding balls of the adhesive tape 10 are mounted are rotatably mounted above the start end of the pressing belt 7 and below the end side of the conveyor belt 5, The tapes 10, 10 pulled out from the winding balls mounted on the rollers 11, 11 are guided to the pressure rollers 13, 13 which are fixed to the shafts of the pulleys 4, 8 on the conveying end side through the guide rollers 12, 12. The delivery side of the conveyor belt 5 and the pressing belt 7 is rotatably supported by the three guide rolls 14 on the left and right and the upper side, and at the same time, the one guide roll 14 is used as a drive source. A rotating ring 15 is provided. As shown in FIG. 4, a reel 17 around which a black thread 16 is wound is rotatably and detachably rotatably supported on the ring 15, and the drawn thread 16 passes through a cord brake 18 and a needle 19 projecting in the vicinity thereof. It is led out from the hole at the tip. Then, the thread 16 guided out from the needle 19 is continuously wound around the tape 10 for sticking the seedling row as the ring 15 rotates. A limit switch 20 is provided in the line drawing passage between the string brake 18 and the needle 19, and the limit switch 20 is directly connected to the battery 22 provided on the base 21, the changeover switch 23 constituting the main switch, and the buzzer 24. It is connected to the. Therefore, when the limit switch 20 is turned on due to thread breakage or no thread breakage, the buzzer 24 operates to notify the operator of the occurrence of thread breakage.

On the delivery side of the ring 15, seedling support rollers 25 and 26 made of rubber are vertically opposed and are rotationally driven in opposite directions. Further, as shown in FIG. 3, the lower seedling support rollers 26, 26 'are fixed to the shaft 27, and a large number of axial protrusions 26a having a receding angle on the outer peripheral surface of the rollers 26, 26'. Is formed. In particular, among the seedling support rollers 26, 26 ', the seedling support roller 26' on the side closer to the plant base is provided at a rear position extremely close to the rotational trajectory of the needle 19, so that the needles project downward into the seedling row. According to No. 19, the mounting position is selected so that the seedlings that are going to be swung downward can be scraped up well and the seedlings will not be wound together with the thread and cause planting defects such as dislocation and breakage when planting the seedlings. Further, a drum 28 for winding the seedling row is provided on the lower side of the seedling support rollers 25, 26 in the conveying direction. The drum 28 is detachably mounted via a snap pin 35 to a winding shaft 34 which is rotationally driven by a motor 29 via a speed reducer 30, a torque limiter 31, and sprockets 32 and 33. Further, the drum 28 rotates integrally with the winding shaft 34 by aligning a notch provided on the boss with a pin 34a protruding from the winding shaft 34. The torque limiter 31 temporarily stops the rotation of the drum 28 in synchronization with the take-out speed of the seedling row as the winding amount of the drum 28 increases.

On the other hand, a sensor for detecting the winding amount of the tape seedling A wound on the drum 28 is provided below the drum 28 and the seedling support rollers 25, 26. The sensor is composed of a sensor arm 37 whose base is rotatably supported by a fulcrum shaft 36, and a limit switch 38 fixed to one end of the sensor arm 37. A roller 39 is rotatably supported at the other end of the L-shaped sensor arm 37. The roller 39 is attached by a spring 40 attached across the sensor arm 37 and the machine frame 3. It is urged to rotate while always contacting the side plate of the drum 28. Then, the limit switch 38 has the tape 10 adhered on both side surfaces thereof, and the actuator faces the tape corresponding portion of the tape seedling A threaded by the needle 19 and is connected to the electric circuit shown in FIG. ing. The electric circuit includes a motor drive circuit including a 200-volt three-phase AC outlet 41, a main switch 42, and a taping machine drive motor 29, a limit switch 38 attached to the motor drive circuit, and an AC buzzer 43. It is composed of

Next, the tape seedling manufacturing process of the tape seedling manufacturing machine will be described. In the work, first, the main switch 42 is pressed to drive the motor 29. Although detailed description is omitted, the motor 29 drives each part of the unwinding machine 1 and the taping machine 2 via the transmission device such as the speed reducer 30 described above. Here, when the root-entangled seedlings of strawberries are supplied to the supply port B of the unwinding machine 1, the unwinding machine 1 loosens the root stock, and continuously transfers the seedlings on the conveyor belt 5 of the taping machine 2 and the root conveyor belt 5a. And carry it out. Then, the transport belt 5 and the root transport belt 5a transport the seedling row in the left direction in FIG. 2, and then the seedling row is nipped and transported by the transport belt 5 and the pressing belt 7 and reaches the vicinity of the end. Then, the cutter 9 finishes and cuts the tip of the stem, and the seedling row is sent out from both belts 5 and 7. At this end, the upper and lower tapes 10 and 10 are pulled out and pressure-bonded to both side surfaces of the seedling row on the side closer to the plant by the pressure-contact rollers 13 and 13. Next, the needle 19 pulls out the thread 16 while rotating together with the ring 15, and continuously winds the thread around the upper and lower adhered tapes 10. The tape seedling A fed in this way is wound around the winding drum 28.

Further, when the work is continued and the tape seedling A is wound on the drum 28 by a predetermined amount, the limit switch 38 fixed to the sensor arm is brought into contact with the tape portion of the tape seedling A wound on the drum and turned on. Become. As a result, the buzzer 43 is activated to notify the operator that it is time to replace the drum. Therefore, the worker pushes the main switch 42 to turn off the motor drive circuit and the alarm circuit, and then performs the drum replacement work. In this case, when the drum 28, which has been wound up by a predetermined amount, is removed from the winding shaft 34, the sensor arm 37 is retracted by the spring 40 to the position shown by the chain double-dashed line in FIG. Therefore, when the drum is removed, the limit switch 38 does not interfere with and damage the drum 28, and when a new drum is set, the sensor arm 37 returns to its original position, and the limit switch 38 moves inside the drum 28. Since it enters the predetermined position of, the drum replacement work can be performed quickly.

When the drum replacement work is completed, the motor 29 is started again and the work is continued. When the tape seedling manufacturing work described above is completed, the tape seedlings A are stored in a storage box 44 of the transplanter in a zigzag shape as shown in FIG. In this case, the drum 28 is supported by a dedicated stand 45, and the worker sequentially pulls out the tape seedlings A and stores them in the storage box 44. In particular, when the boss portion 28a of the drum 28 and the receiving portion 45a of the stand 45 are formed in a polygonal shape as shown in FIGS. 8 and 9, rotation resistance is imparted when the tape seedling A is pulled out from the drum 28, The tape seedling A is not pulled out more than necessary, and the storage work can be performed smoothly.

In the above-described embodiment, when the sensor (limit switch 38) for detecting the winding amount detects the winding of the tape seedling of the predetermined amount, the buzzer is activated to notify the operator. However, when the sensor detects a predetermined amount of winding, the drive circuit of the motor may be disconnected and the entire drive may be stopped. In that case, after the sensor is activated, the motor drive circuit is continuously disconnected until the separately provided reset button is pressed, and the motor restarts unexpectedly even when the sensor is restored due to drum replacement work. It is preferable in terms of safety to configure the circuit not to do so. Further, as the sensor for detecting the winding amount, in addition to the contact-type sensor shown in the embodiment, a non-contact-type sensor such as an ultrasonic distance detector may be used. The winding amount of the stem tip portion may be detected without using the portion as the detection target. Further, the rotation number of the drum 28 is counted by the rotation number detection sensor, and when a predetermined number of rotations is reached, an alarm device is activated or the motor is stopped, so that the winding amount of the drum is secondary. It may be detected.

On the other hand, in the embodiment, the tape seedling A is sandwiched between the conveyor belts 5 and 7 and can be molded to have a substantially constant thickness. Therefore, by making the winding diameters of the tape seedlings wound on the drums the same, the overall volume resulting from the length of the tape seedlings and the thickness of the tape seedlings can be made approximately constant between the drums, and the storage box It does not stick out even if it is placed in No. 44, and the seeding splicing timing at the time of seedling transplantation can be adjusted for each line. However, assuming that the tape seedling itself has a variable thickness, it is premised that it can be stored in a storage box in a good condition, and the overall volume is emphasized. Is sensed so that is constant. Alternatively, if it is desired that the seedling splicing timing at the time of transplanting seedlings be emphasized and the length of the tape seedlings on each drum be kept constant, the length of the tape seedlings should be directly detected and wound on each drum. Take measures to keep the amount constant. As a method, for example, by attaching a rotation speed detection sensor to the guide roller 12 of the tape 10 and activating an alarm device or stopping the motor when a predetermined rotation speed is reached, The length of the tape seedling wound on the drum can be known from the pull-out length of 10, and it is possible to always obtain the tape seedling of a constant length even if the thickness of the tape seedling varies. Therefore, according to the present invention, a sensor for detecting various suitable winding amounts according to each seedling is used to notify an operator by a warning device that it is time to replace the drum, or a seedling manufacturing machine. The respective objectives can be achieved by stopping the driving of the drums and preventing further winding on the drums.

[Effect of device]

 The present invention has a sticking device for sticking the tape 10 on both sides of the seedling row, a drum 28 for winding the stuck tape seedling A, and a drum for winding the seedling A on the both sides of the seedling row in the seedling feeding section of the seedling carrier. A sensor 38 for detecting the winding amount of the tape seedlings is provided, and when a predetermined amount of the tape seedlings A is wound on the drum 28, the sensor 38 detects the winding and the operator is warned that it is time to replace the drums. No. 43 is activated to notify or the drive of the seedling producing machine is stopped to prevent further winding on the drum. Therefore, the winding amount of the tape seedling A wound on the drum 28 is constantly maintained. Since it is free from the trouble of monitoring and the winding amount on the drum 28 can be always kept uniform, it is possible to prevent occurrence of trouble in the subsequent seedling treatment work or machine transplant work.
